Is it use CreateFile() or direct port addressing?

I think to bay USB->Parallel cable. It installs in system as something like 'USB-LPT1' virtual port without any hardware address.

If the display plugin use CreateFile() and have option to select the symbol port name it could be working...

The USB>Parallel adaptor will not work for an LCD because it only emulates some of the printer functions of the port. You need a real LPT port to control an LCD because the driver directly controls the port pins. This can be a PCI/PCIe adaptor card for a desktop PC. For a laptop, you need to use a different system to connect an LCD. You can try LCD2USB if you don't want to do lots of electronics yourself. There are also a couple of projects on this forum that connect an LCD via serial or USB ports.

Hi, the hd44780s works for my vfd 2x20 from Futuba but not 100%.

The text moved and the underline appears double on the vfd.

what does timing multiplexer mean? And whta are the parameters for addressing?
